Here is state Sen. Malcolm Smith sucking up to an undercover federal agent on a clandestine video filmed during a meeting at a Grand Central Terminal restaurant.

The undercover agent met with Smith to discuss how to bribe politicians to support a run by Smith, a Democrat, for mayor on the Republican ticket, prosecutors have said during Smith’s ongoing bribery and corruption trial in White Plains federal court.

“You pull this off, you can have the house [Gracie Mansion]. I’ll be a tenant,” Smith told the agent during one of their meetings.

Smith even boasted that it was acceptable for him to pay his way into Gracie Mansion because that’s “the business of government,” according to tapes of conversations he had with the undercover agent.

But a late disclosure of a trove of recorded phone calls by federal prosecutors has led defense attorneys to demand a mistrial or dismissal of the indictments.
